First Claim
Patent Images
1. A gas generator for a vehicle occupant protection system comprising:
- an elongated cylindrical housing;
a pair of end closures at opposite ends of said housing, respectively;
a radially extending imperforate partition in said housing intermediate the ends thereof defining a pair of discrete propellant combustion chambers; and
a pair of annular crimps in said housing on opposite sides, respectively, of said partition whereby combustion pressure in one of said propellant chambers biases the partition against the crimp on the opposite side thereof to maximize sealing therebetween.

2. A gas generator for a vehicle occupant protection system comprising:
-
an elongated cylindrical housing having a given circumference;
a pair of end closures at opposite ends of said housing, respectively;
a radially extending imperforate partition in said housing intermediate the ends thereof defining a pair of discrete propellant chambers; and
a pair of annular crimps coextensive with said circumference and in said housing on opposite sides, respectively, of said partition whereby combustion pressure in one of said propellant chambers biases the partition against the crimp on the opposite side thereof to maximize sealing therebetween.
